The present invention relates to devices for removing fluids fromvessels as the removal of bilge water from the hull of a ship.

An object of the invention is to utilize the force created by the flowof fluid through a cooling system for creating the necessary suction forremoving fluid from a vessel.

A further object is to provide means whereby the utilization of theforce of the cooling 11 system may be controlled for creating suction ofthe vessel and consists in a vacuum chamber having an outlet separatefrom the outlet as set forth above.

The device by which the above ob ects are accomplished comprisesapparatus adaptedto be connected in a system having a fluid flowingtherethrough such as a 'coohng system used in connection with an engine,

and operated by the flow of fluid-there- 1' through for drawingfluidfrom a vessel by suction. An important accessory to the above device, asoutlined, is that of means, as

a threeway valve, for selectively directing the flow offluid to itscustomary outlet or through the suction device.

An embodiment of the above principles herein illustrated and describedshow an adaptation thereof to the cooling system of an engine used topropel a vessel and as used for the removal of bilge water from the hullof the cooling system and means therein for creating a vacuum when fluidfrom the cooling system is permitted to flow therethrough. The flow offluid through the system and through :its usual outlet is controlled bya threeway valve and a hose orpipe is provided connected with vthevacuum chamber and having ahead adapted to be vice constructed as aboveis set in operation it effectively exhausts fluid from a vessel incidentto the flow of the cooling fluid of the engine to the outlet.

Referring to the drawings in detail, a numeral 10 designates the wholevessel, 11 the engine for propelling the same, the engine being providedwith the usual water jacket arrangement which is not specificallyillustrated in the present embodiment inasmuch as it involves none ofthe principles of the invention. To this jacket is'connected an in letconduit 12 having a pump '13 connected therewith and adapted to drawwater from the floating medium for the vessel, through the conduit 14leading from a suitable opening in the side of the vessel; After thefluid has been forced through the jacket of the engine it is allowed toescape through the outletconduit 15 having an opening communicating inthe side of the vesselas at 16.

' A branch outlet conduit 17 is connected to the conduit as at.18 andthe vessel is providedwithan aperture 19 similar to that at 16 intheside of the vessel with which this conduit communicates as in thecase of the branch 15 and the outlet 16. The conduit 17 has formedtherein an enlargement provid- Ing a cha-mber 20which may be known as avacuum chamber in which a vacuum or suetlonmay be created by a suitabledevice as a nozzle 21 projected thereinto from the side of said chamberconnected with the conduit 15. 7 The flow offluid through theconduit'15, apertures 16 and 19 may be selectively controlled through athreeway valve 22 positioned in a suitable seat 23 formedin the con duit15 opposite the connection thereof with the conduit 17. This valve whenturned to one position will permit the customary flow of fluidin theconduit 15 to the opening 16 and when in another position, will directthe flow through the nozzle2l by which it will be projected intovtheVenturi tube 24 and out throughthe opening 19. The valve 22 may beprovided with a handle 28 for turning the same and with a pointer 29movable over a dial 30 secured to the valve seat and having indicationsmarked thereon instructive of the position of the openings through thevalve within its seat.

A suitable conduit 25 in the nature of a pipe or a flexible hose may beprovided and connected to a stem 26 having its bore in communicationwith the vacuum chamber 20 and preferably in a position below the nozzle21. The lower end .of this pipe or hose may be provided-with a head 27of any suitable character for admitting the bilgewater to the conduit 25and preferably for preventing large particles from passing therethrough.The end of the nozzle 21 which is of the type known as the high speednozzle is preferably projected slightly into the mouth of the Venturitube or as shown in the drawings may extend to a point short of theVenturi tube.

Inoperation, when there is bilge water to be removed, the pump 13 isoperated in the usual manner drawing water from the floating medium forthe vessel and forcing the same through the water jacket of the engineand outthrough the conduit 15 by which it is discharged back into thefloating medium through the aperture 16, the valve 22 being turned to ap'ositionso that the flow will be cut off from the branch conduit 17.VVhenever it is desired to use the force of the flow ing partly acrossthe dome but stopping short of complete traverse, said nozzle having aconical passage in axial alinement with and the apex directed toward theoutflow pipe, and means to variably by-pass water from said dischargepipe through said nozzle into the outflow pipe.

offluid through the cooling system to draw the bilge water from thebottom of the vessel, the valveis turned to a position as shown inFigure .3 in which position the fluid is projected through the nozzle 21into the Venturi tube 24, thereby creating a vacuum in the chamber 20and causing a suction at the head 27 whereby the bilgewater isdischarged together with that of the cooling system through the aperture19 in the side of the vessel. It is to be understood that the principlesof the invention may be applied wherever flowing fluid is directedthrough a conduit having a discharge. However, the principles areespecially adapted to systems which are in constant operation for otherpurposes as for the cooling of an area such as that defined by an engineas in the present instance. I do'not, therefore, wish to be limited inthe scope of my invention to the specific embodiment here disclosed andbelieve that I am entitled to broad protection on the application of'therinciples of the invention as herein set fortii.
